I quote the article :
In the last post, we have already figure out how to connect to the firebird database in Linux/UNIX environment. In this post, I will use application built in Qt framework to connect the firebird database and do simply task.
To allowing Qt applications connect to the firebird database, we need some tools, here I introduce the IBPP project.

The Qt toolkit contains many great SQL drivers and among them is also an InterBase / FireBird SQL driver. But the Windows version of the toolkit ships with SQLite and ODBC driver binaries only. The other ones have to be built by ourseleves. This article describes how to build the FireBird driver using MinGW 32bit version of Qt 4.6 for Windows.

The project is currently in a semi-working state. My co-worker is
working with Qt to create a searchable list-view that can handle HUGE
amounts of data with astounding user experience and without the quirks
that most SQL list implementations have.
I’m going to write up a new article on this topic with more details
maybe this weekend or next week, so stay tuned. I’ll contact you when
it is finished so you can put it up on firebirdnews.org.

ED:also i love arora and i started to like qt , I’m not an c++ lover
but with qt I started to like it

C++ is just one of the most cleanest languages that are around
(although it has many quirks and is not what I would really call
“clean”, but it’s still “one of the cleanest”). It’s the only language
that solved the resource allocation/deallocation problem in the best
possible manner. See RAII vs. Garbage collection here:http://daniel-albuschat.blogspot.com/2007/11/raii-as-alternative-to-garbage.html

On an unrelated side note, have you ever used Sinática Monitor
yourself? It sounds like a cool product, but I’m wondering how it
works. I have a similar project in mind that would work as a
Firebird-“Proxy” and sniff the communication between the client
application and Firebird. But Sinática even has info on server and I/O
loads, that really cool.

pretty off-topic here, but IMHO even interesting for Firebird users,
because Firebird/InterBase can be accessed via the QT framework.

Formerly licensed under GPL and a commercial license for closed source
development, releasing QT under LGPL is a very “interesting” move from
Nokia.

Especially for QT-based embedded devices, Firebird might be an
interesting option for an embeddable database, if:

* there is a stable Firebird specific (not the current InterBase one,
even if it might work now) QT SQL driver/module implementation available
* Firebird is cross-compilable for ARM, … (something which has been
discussed on firebird-devel from time to time. AFAIK, there is a private
ARM port of Firebird somewhere)
